P. J. KELLY WINDOW sAsH FASTENER Filed June l0, 1957 2 Sheets-Sheet 2 Patented Sept. 20, 1938 stares PATENT lorties 2 Claims.

This invention relates to fasteners and retainers for window sashes of the double duty sliding type used in present day house construction, that is, the vertically slidable sash assemblage utilizing associated pulley and weight suspending or counterbalancing means.

My primary aim is to provide a structurally distinct and aptly tted so-called sash lock wherein the complemental parts are mounted on the respective companion sashes, one part being characterized by rigid detents, and the other part by a spring pressed, manually released pivoted latch.

Needless to say, I am suioiently conversant with the art and the trade to realize that fasteners have been provided for locking window sashes in partially open position to promote free ventilation and to at the same time guard against unauthorized entry of intruders. It follows, therefore, that I aim to accomplish this now fundamentally old result through the instrumentality of a novel and improved structure, that is, a structure possessed of such structural distinction and renement to lend itself admirably well in serving intended purposes and which will otherwise fulll the requirements of the trade and users.

Other features and advantages will become more readily apparent from the following description and accompanying drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a fragmentary perspective View showing a portion of an upper and complemental lower sash with the improved lock or fastener in place, the sashes being locked in wholly closed positions.

Figure 2 is a perspective view of one of the complemental parts which may be identified as the relatively fixed detent or keeper plate.

Figure 3 is a longitudinal or horizontal sectional view taken approximately on the plane of the line 3 3 of Figure 4.

Figure 4 is an end elevation which may be conveniently designated as an inner end elevation of the relatively movable unit seen in Figure l.

Figure 5 is an enlarged fragmentary sectional view looking in the direction of the arrow from left to right in Figure 1.

In the drawings the upper sash is indicated by the numeral 6, and the lower companion sliding sash is indicated by the numeral l. These are of conventional construction. It might be asserted, however, that in the arrangement seen in Figure 1, the upper sash is provided with a central stile such as is used in certain twin-panel window construction. This is denoted by the numeral 8, and in some instances the detent plate or strip 9 may be secured thereto. This strip 9, however, is applicable, by slight revision, toeither of the vertical frame members of the sash frames. It is simply fastened in place, as seen in Figure l, by screws or the like Ill. The main characteristic thereof is the incorporation therein of the vertically spaced, outstanding projections I I, these being substantially triangular and constituting keepers or detent lugs.

As before stated, the part or unit 9 is the relatively stationary part in the ordinary sense of the word.I That is to say, it is generally considered as fixed in relation to the relatively slidable unit I2. This unit or part I2 is characterized by a substantially rectangular box-like casing I3 having its top and bottom walls projecting to fo-rm flanges I 4 to conveniently accommodate the manually manipulated spring pressed latch I5. The latch is a simple strip of metal of general rectangular form having intermediate its ends a pair of spaced parallel duplicate ears IB, these being swingably or pivotally mounted on the pivot pin Il. The numerals I8, incidentally, denote the attaching screws for the complete unit I2. The eiective or retaining end of the latch projects beyond what may be called the left-hand end of the casing as seen in Figure 5, where its under edge is beveled or cut, as indicated at I9, to ride down over the detent lugs II in ratchetlike fashion, this being accomplished against the tension of the coil spring 2D. The spring is mounted on the pivot pin between the ears I6, and one free end is anchored in the casing, as indicated at 2|. The opposite free end is anchored in the free' swingable end of the latch, as indicated at 22. The detent engaging eXtension or end of the latch is provided with an upstanding or vertically disposed projection 23, this having an appropriately shaped aperture 24 formed therein to provide what may be conveniently called a keeper seat or adapter for the selectively engageable detents or lugs I I.

Assuming that the sashes are in closed position, as seen in Figures 1 and 5, it is obvious that spring. Holding the latch in this position, it is evident that the device becomes temporarily ineffective. It is possible to release the latch so that it will engage the extension 23 underneath either of the detents Il, or so that the aperture 24 will engage over the detents, whichever is preferred. It has been found advisable to provide this apertured extension 23, since it serves to provide not only a desirable retaining action, but prevents separation, that is, lateral separation, of the sashes 6 and 1, whereby to function as an anti-rattler element.

It is thought *that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. 'I'herefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming Within the eld of invention claimed may be resorted to if desired.

I claim: 1. As a component part of a sash retainer of the class described, a substantially box-like casing including upper and lower spaced parallel flanges and a centrally disposed pivot pin, a latch including upper and lower spaced parallel ears pivoted on said pivot pin, said latch having an apertured keeper extension at one end, a spring mounted between said ears and surrounding the pivot pin, having one end anchored on the casing and the opposite end anchored to the intermediate portion of the swingable latch.

2. As a component part of a sash retainer construction of the class described, a substantially box-like casing including, top, bottom, end and one longitudinal side wall whereby to render the casing open along one longitudinal side, a centrally disposed vertically arranged pivot pin in said casing, a longitudinally elongated plate forming a latch and disposed in the open side of said casing and provided with spaced parallel ears pivotally adjoined to said pivot pin, one end of the latch extending beyond the corresponding end of the casing where it is beveled and provided with an upstanding apertured keeper extension.
